What ASVAB score do I need for the Marines?

Two things. To enlist, the Marine Corps publishes a minimum ASVAB (AFQT) score of 31, or 50 with a GED or nontraditional diploma. Past that, each MOS prints its own composite score in the MOS Manual. In the FY27 manual (NAVMC 1200.1M) the primary MOSs open to privates run from GT 85 for 3152 Distribution Specialist, and EL 85 or MM 85 for 3531 Motor Vehicle Operator, up to 110: GT 110 for 0241 Imagery Analysis Specialist, CL 110 or GT 110 for 1721 Cyberspace Warfare Operator and EL 110 for 2831 Digital Wideband Systems Maintainer.

What are GT, MM, EL and CL?

The four Marine Corps composites. The ASVAB program publishes how each is built: GT (General Technical) is VE + AR + MC, MM (Mechanical) is AR + MC + AS + EI, EL (Electrical) is AR + EI + GS + MK and CL (Clerical) is VE + MK. The MOS Manual treats them as composite standard scores, so use the GT, MM, EL and CL numbers on your score report instead of adding subtests yourself.

What ASVAB score does Marine infantry need?

In the FY27 MOS Manual, 0311 Rifleman, 0313 Light Armored Reconnaissance Marine and 0341 Mortarman each need CL 90 or GT 90. 0331 Machine Gunner needs EL 90, GT 90 or MM 90, and 0352 Antitank Missile Gunner needs GT 95 or MM 95. 0321 Reconnaissance Marine needs CL 105 or GT 105, and the manual calls that prerequisite non-waiverable.

What ASVAB score do Marine intelligence and cyber MOSs need?

0231 Intelligence Specialist and 0261 Geospatial Intelligence Specialist need CL 110 or GT 110, and 0241 Imagery Analysis Specialist needs GT 110. 1721 Cyberspace Warfare Operator needs CL 110 or GT 110, and accession Marines also need a cyber-test score of 55 or higher. 2641 Cryptologic Language Analyst needs CL 110 or GT 105, and assignment to the Defense Language Institute requires 100 or higher on the DLAB.

How is the Marine Raider MOS (0372) qualified?

The FY27 manual lists 0372 Marine Raider as a primary MOS for sergeants through master gunnery sergeants, so it is not open to privates. Its prerequisites include a GT score of 105 or higher and U.S. citizenship. Marines from any MOS with at least 24 months in service may volunteer for assessment and selection, and the manual adds physical standards and security requirements that this page does not score.

Can a Marine Corps composite score be waived?

The MOS Manual mostly does not say. Eleven enlisted MOSs mention waivers in the score prerequisite itself. 0321 Reconnaissance Marine and 2147 Light Armored Vehicle (LAV) Repairer/Technician call it non-waiverable, and 7314 Sensor Operator (SO), MQ-9 says no waivers. 4421 Legal Services Specialist prints CL 110 as not waiverable and GT 105 as waiverable to 102.

What changed in the FY27 Marine Corps MOS Manual?

NAVMC 1200.1M replaced NAVMC 1200.1L on 1 October 2026. In the enlisted chapter it adds 6 MOSs, deletes 1 (2146 Heavy Ordnance Vehicle Repairer/Technician), changes the composite score of 8 and marks 5 more as obsolete. Two examples: 7051 Aircraft Rescue and Fire Fighting (ARFF) Specialist went from GT 90 or MM 90 to MM 95, and 7251 Air Traffic Controller-Trainee from GT 110 to CL 110 or GT 110.

Are Marine aviation maintenance MOSs scored like Navy ratings?

No. A Marine MOS prints a composite score: 6217 Fixed-Wing Aircraft Mechanic, F/A-18 needs CL 105 or MM 105. The Navy prints sums of subtest scores instead: in the Navy Recruiting Manual of 5 August 2026 its Aviation Machinist's Mate (AD) rating takes VE+MK+AS≥158 or VE+MK+EI≥155.

Yes. On the computer version given at a MEPS or MET site, every subtest has its own time limit. Without tryout questions the limits run from 6 minutes for Shop Information and 7 for Auto Information to 31 for Mathematics Knowledge and 55 for Arithmetic Reasoning; they are longer when unscored tryout questions are added. The testing program says almost all examinees finish each subtest before the time expires and that the test takes about 2 hours on average. The PiCAT, the unproctored version you take with a recruiter's access code, has no time limits on the individual subtests.

Can you use a calculator on the ASVAB?

No. Calculators are not allowed on the ASVAB. The testing program's explanation is that the ASVAB is an employment test meant to show whether you can apply principles to solve problems, so Arithmetic Reasoning and Mathematics Knowledge are worked by hand. Practice without a calculator, because that is how the score that counts is earned.

How the Marine Corps uses ASVAB scores

Two kinds of score come out of one ASVAB. The AFQT, a percentile computed from four subtests (Arithmetic Reasoning, Mathematics Knowledge, Paragraph Comprehension and Word Knowledge), decides whether you can enlist: the Marine Corps publishes a minimum of 31, or 50 with a GED or nontraditional diploma.

The composites decide which MOSs are open. The Marine Corps uses four, and the ASVAB program publishes how each is built:

GT — General Technical: VE + AR + MC (the ASVAB program's table calls it General Technician)
MM — Mechanical: AR + MC + AS + EI
EL — Electrical: AR + EI + GS + MK
CL — Clerical: VE + MK

AR is Arithmetic Reasoning, MK Mathematics Knowledge, MC Mechanical Comprehension, AS Auto and Shop Information, EI Electronics Information and GS General Science; VE is the verbal score built from Word Knowledge and Paragraph Comprehension. The MOS Manual refers to the results as composite standard scores, which is why its prerequisites read 85 to 120 and not as a sum of subtests: enter the composites from your score report, not your subtest scores.

Composite formulas and AFQT subtests: ASVAB Testing Program. Enlistment minimum: marines.com, Requirements.

How to read an entry

Primary MOS (PMOS): the manual's glossary says “Used to identify the primary skills and knowledge of a Marine.”
Basic MOS: the manual's glossary says “Entry-level MOSs required for the P2T2 T/O for entry-level Marines or others not yet qualified by initial skills training.”
Necessary MOS (NMOS): the manual's glossary says “A non-PMOS that has a prerequisite of one or more PMOSs.”
Free MOS (FMOS): the manual's glossary says “Non-PMOS that can be filled by any Marine regardless of primary MOS.”
Exception MOS (EMOS): the manual's glossary says “Non-PMOS that is generally FMOS but includes exceptions that require a PMOS.”
Grades: the range in the MOS heading. “MGySgt to Pvt” is an MOS a private can hold; “MGySgt to SSgt” is reached later in a career.
“or”: either score qualifies. “and”: both are required.
No composite score: the MOS's prerequisites name none. Many senior and additional MOSs instead require holding another MOS.
Obsolete: the manual marks 21 enlisted MOSs as no longer on the table of organization and keeps them because Marines still hold them.
FY26 manual: shown where the score or the title differs from NAVMC 1200.1L, the manual this one replaced.

Tests other than the four composites

6 MOSs name another score in their prerequisites: the AFQT as an alternative to a composite, the verbal score, a cyber test, the English Comprehension Level test or the Defense Language Aptitude Battery.

0211 Counterintelligence/Human Intelligence (CI/HUMINT) Specialist: “Must possess a minimum GT score of 105, or a minimum CL score of 105, or a minimum AFQT score of 55.” “Must have a DLAB test score in their OMPF. There is no minimum DLAB score required before being assigned the 0211 PMOS.”
0367 Light Armored Reconnaissance Master Gunner: “Must have an ECL score of 90 or above.”
1721 Cyberspace Warfare Operator: “Accession Marines must possess a cyber-test score of 55 or higher.”
2641 Cryptologic Language Analyst: “Assignment to DLI requires a minimum score of 100 or higher on the Defense Language Aptitude Battery (DLAB). The DLAB score may be waived on a case-by-case basis if significant foreign language experience is demonstrated, or a GT score over 110 is achieved and if such a waiver is requested by the Recruit Screening Office at the applicable Marine Corps Recruiting Depot and approved by Headquarters Marine Corps, Intelligence Division.”
4500 Basic Communication Strategy and Operations Marine: “Must have a VE score 45 or higher.”
6033 Aircraft Nondestructive Inspection Technician: “Must have a minimum AFQT score of 55 or a minimum GT score of 105.”
